1) repeat visitors do not have to put their name/email every time they want to post, so using a popular blog will get more people to post on my blog
2) easy to make changes
But I'm also leaning on not moving because:
1) I don't like the mandatory toolbar along the top
2) I'm comfortable coding the html/css/php by myself, so the settings that allow you to change colors, etc. isn't that useful to me
3) I can just use cookies to keep track of repeat visitors, which would solve problem #1.
Can any bloggers answer?
